GRAIIN-WEIGHINVG SCALE.

SPECIFICATION forming part of Letters Patent No. 393,888, dated December4, 1888. Application filed April 23, 1888. Serial No. 271,595. (Nomodel.)

To all whom it may concern:

Be itknowu that-I, HENRY CUTLER, of North \\-'ilhraham, in the county ofHampden and State of Massachusetts, have invented a new and ImprovedAutomatic Graineighing Scale, of which the following is a full, clear,and exact description.

The invention relates to weighing-scales such as are shown. anddescribed in Patent No. 375,267, granted to me December 20,1887.

The object of the invention is to provide a new and improved scale forweighing grain which is simple and durable in construction, not liableto get out of order, and is automatic in operation, delivering theweighed grain to the bags.

The invention consists of certain parts and details and combinations ofthe same, as willbe fully described hereinafter, and then pointed out inthe claims Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure 1 isa side'elevation of the improvement with parts in section.Fig. 2 is an enlarged perspective view of the lower part of thebag-support. Fig. 3 is an enlarged side elevation of one of thescale-beams. Fig. 4 is a plan view of the same. Fig. 5 is an enlargedperspective view of the knife-bearing, and Fig. 6 is a sectional sideelevation of the improvement on the line on at of Fig. 1.

I The improved weighingscale A is provided with a base, B, in the middleof which is erected a standard, B, carrying a bracket, B extendingequally on both sides of the standard B and carrying in its middle abearing, 0, on which is mounted to turn an oscillating lever, D,carrying at its upper end a cylinder, E, extending equally on both sidesof the said oscillating lever D. The ends of the cylinder E are adaptedto rest alternately on the stops F and F, secured on the bracket B andin the said cylinder travels a ball similar .to the one described in thepatent above referred to.

The ends of the cylinder E are also adapted to strike alternatelyagainst the arms G and G, pivoted at their lower ends to the bracket Band at their other ends pivotall y connected to the horizontal bar H,mounted to slide in suitable bearings formed on the front of thestandard B"? The arms G and G may be rigidly secured to the bar H inorder to move the latter when struck by the respective end of thecylinder E. The bar ll is provided in its middle with the lugsl-I.,between which is held a pin, I, secured to the oscillating hopperI, fulcrumed at I to the upper end of the standard B. The pin 1 passesthrough the segmental slot I formed in the front of the standard B. Thehopper I is provided with a transverse partition, I", thus forming twocompartments adapted to connect, respectively, with the upper ends ofthe chutes J and J, extending downward in opposite directions andopening into the cone-shaped hoppers K and K, secured by suitableflanges to the longitudinal beam B secured to the standard B andsupported at its ends by posts 13'', resting on the base B. Adeliverychute, I, is held above the upper end of the hopper I anddischarges alternately into the two compartments of the hopper I,according to the position of the latter, and the respective compartmentconnects with its chute J or J, so that all clogging is prevented.

The hoppers K and K open into the cylinders L and L, respectively, eachprovided on its outside with pins L on which the mouths of the bags aresecured, the bags fitting around the cylinders L or L, respectively. Thecylinders L and L are supported on the frames N and N, respectively,connected at their upper ends by links 0 and 0, respectively, with thescale-beams P and P, respectively, fulcruined on the links Q and Q,respectively, pivoted at the outer ends of the bracket B The scale-beamsP and P are also connected by the links R and-R with the slotted links Rand R respectively, pivotally connected with the poises S and S,respectively, adapted to rest in their lowermost positions on thebracket Bflsecured to the standard B.

The links R and R are slotted, so that the links R and R move freely inthe same until the scale-beam P or P, respectively, is in nearly ahorizontal position, after which the links Rand R lift the links R andR" and the poises S and S, respectively, as hereinafter more fullydescribed.

The scale-beams I and P are also connected with the oscillating lever Dby links T and T, the levers D and D and the arms D and I) in the samemanner as described in the patent above referred to. The links T and Ttake the place of the S-shaped hooks. On IO the lever D is pivoted apointer, U, which extends upward and passes through a slot in theguide-arm E, secured to the cylinder E. In the slot of the guide-arm Eare held adjust ably the set-screws E and E so that the i5 movement ofthe pointer l in the said slot-of the guide-arm E can be increased ordiminished. This pointer serves as a balancingpoise, and it is allowedby the screws E and E to go out farther from the center in order toincrease or diminish the load tobe weighed. The bearing-points of thescale-beams P and P are made in the following manner, and

as fully illustrated in Figs. 3, 4, and 5: Each scale-beam P or P. is'provided at its ends with the slot-ted heads P and P of which the head Pis provided with two bea-ring-point-s one on its under side and one ont0pto accommodate the links Q and O or Q and O,-

respectively, and on the other head, P are 0 formed two bearing-pointson its top edge to accommodate the links R T or R T. bearin g-poin t ismade by two pins, P, inserted in corresponding slots in the sides of theheads.

P and I, and a V-shaped groove, 1 is filed into each of the said pins P.Thus when'thev V -shaped groove is worn out by constant use of the scalethe respective pin P can be removed from the head of the beam P or P andreplaced by anew one. In each V-shaped 4o groove P of each bearingfitsthe knife-edge O of a block, 0 held by the respective links 0 O, Q Q, RR, and T T. Said links are fitted over a slot, 0, in the said blockO",and

at each end of the knife-edge O, and in line 5 with the same, is formedapivot, 0, bearing against longitudinal bars I secured to projectiuglugs P on the said heads P and P by set-screws or other suitable means,thus.

holding the blocks 0 and their connectinglinks in place. Thus the linkssecured to the .blocks 0 are prevented from moving on account of beingheld inthe slots 0 and the blocks 0 are prevented from moving endwise bythe pivots O, resting against the 1011- 5 5 gitudinal strips P. In themiddle of each scalebeam P or P is secured a pointer, P,

pointing. on the outside of a marking-bar, P secured to the bracket Band serving to indicate the correct weight when the pointer 6 reaches acorresponding mark or line on the bar P Ea h ba -frame N or N is rovidedwith.

a bottom-,- l\*, on which rests the bottom of the bag, and the saidbottom N is held vertically.

s di table=. t-h mes d bym ns of thumb-screws N passing through one ofEach BEST AVAlLABLE cop- .vided with a lug, X adapted to engagethe rearend of the base l'l,'as shown in 'l ig. H. A crank-arm, V, is adapted tooperate against the rear of the said guard N, so that thebagframe N orNwill swing forward and beheld in place while the filled bag is beingreplaced by an empty one. The bag-frame N or X, respectively, is thenpressed with its upper end agaiiist the lugs K oi. the hoppers it or Kand the lug N is firmly pressed against the base B, so as to prevent thelHlg-fl'tllllt from moving. The crank-arm Y is secured on a shaft, V,mounted to turn in suitable hearings on the posts 1-3 and the standard1%. A lever, V is secured on the said shaft and serves to turn saidshaft so as to engage its crank-arm V with the respective bag-frame N orN or disengage it from the same.

The operation is as follows: \Yhen the machine is in the. position shownin Fig. .l, the oscillating hopper I discharges into the spout .I, sothat the grain passing down the latter falls into the cone-shaped hopperK, and from the latter passes into the qvlinder 1., around which hangsthe bag to be filled, so that the grain falls from the said cylinder 1.directly into the bag, resting with its bottom on the bottom N of t-h'eframe N. When the grain falls into the cone-shaped hopper. 'K, its fallis broken and the grain revolves on account of the shape of the saidhopper K before it enters the cylinder I.. When the desired amountofgrain has: 2l('( llllllll;ll'0(l in the bag, the bag-frame N swingsdownward, so that the link 0, acting on the oulerend of the head I ofthe scale-beam 1, causes thesaid head I to swing downward, the fillcrumbeing the link'Q. The other head, P", of the scale-beam I swings upwardand acts by the link T on the lever I) and the arm D of the oscillatinglever D, so that the latter is caused to swing to the other side. Thelink T -then hangs free, and the link R now engages the upper end ol.the slotted link R and the poise S is lifted to prove the accuracy ofthe automatic weight of the load on the frame N. The movement of thelever D causes the cylinder E to swing to the other side, so that theleft-hand end of the cylinder E is thrown in contact with the arm G andcauses the latter to swing to the left, so that the bar H is movedsimilarly andacts by its lugs II onthe pin I',-so that. the hopper Iisshifted,'and its lower end now opens .into the spout J. The cylinder Ethen rests with its left end on the stop F. The grain passing accessintothe hopper I passes down the spout .T into the cone-shaped hopper Kand into the bag suspended from the cylinder L of the frame N. The sameoperation as above described is repeated. The filled bag on the frame Nis now removed and replaced by an empty one, whereby the poise S againcauses -the scale-beam I to assume the position shown in Fi 1 as soon asthe filled bag is removed. The swinging motion of the pointer U,connected with the oscillating lever D, is changed according to theweight of the bags by adjusting the thumb-screws E and E so that themovement of the said arm is increased or dim i n ishcd, and consequentlymore or less power is required for the scale-beams P and I to change theposition of the oscillating lever D by the links '1 and T engaging thelevers D and D and the latter the arms D and D of the said oscillatinglever.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is g 1.
